6. A painter sets a ladder up to reach the bottom of a second-story window
16 feet above the ground. The base of the ladder is 12 feet from the house.
While the painter mixes the paint, a neighbor's dog bumps the ladder, which
moves the base 2 feet farther away from the house. How far up the side of
the house does the ladder now reach?

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!

c. side angle side. u shares the same sides

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

answer: yes, since the line has a steeper rate of change than the exponential the y-values will be greater and they will only intersect one time.
